When approaching a multi-lane roundabout where you intend to take the first exit (turning right), how should you position and signal your vehicle?

1. Approach in the right-hand lane, signal right before entering the roundabout, maintain the outer lane, and exit while continuing to signal right
2. Approach in the extreme left lane, cut across all lanes at the exit without signaling
3. Signal left on approach, enter the inner lane, and turn right abruptly across traffic
4. Do not use turn signals until you are already on the exit road
